Modifying your own details in the Exchange Global Address List (GAL)
I was talking to one of the delegates attending IT Forum who was having challenges with users changing their details in the Global Address List (GAL) and causing lots of administration work for the Exchange administrators. He wanted to know if it was possible to give users permission to edit their own personal information (mobile, office location, title...) in the GAL Each user should have permission to edit only their information not the information of anyone else. Users must be administrators of their own personal information only.
If you want to do this, you can use GALMOD or the Web Based Gal Modify Tool from the Back Office Resource kit if you need to reduce the load on your own Exchange Administrators.
